| 摘要 |
The invention relates to a method and apparatus for quickly and automatically centering and inserting substantially parallel cylindrical or conical measuring objects having very different nominal diameters, such as a smooth axis, outside screw thread, smooth bores, and inside screw thread, in a one-axis measuring system such as, for instance, a universal one-axis measuring machine, with a view to enabling accurate measurement of diameter quantities, such as minor diameter, pitch diameter and outside diameter of screw thread, without it being necessary that, preceding the measurement, first the points of reversal have to be manually searched for, while the influence of the centering clamping force upon the magnitude of the measuring forces between the two measuring plungers and the surface of the measuring object is very small or nil.
